USL is an object-oriented scripting language written with C++ and compiled on both Linux and Windows. Without a script provided, USL is an interactive interpreter and programmable command shell. There is no socket programming with USL. USL is intended for general purpose scripting in local systems.

Google Hacks is a compilation of carefully crafted
Google searches that expose novel functionality
from Google's search and map services. For
example, you can use it to view a timeline of your
search results, view a map, search for music,
search for books, and perform many other specific
kinds of searches.

Ficl (Forth inspired command language) is an ANS Forth interpreter written in C. Unlike traditional Forths, this interpreter is designed to be embedded into other systems as a command/macro/development prototype language. Ficl provides object extensions that can be used to wrap methods and structures of the host system without altering them.

Swami is an instrument patch file editor using SoundFont files that allows you to create and distribute instruments from audio samples used for composing music. It uses FluidSynth, a software synthesizer, which has real time effect control, support for modulators, and routable audio via JACK. This project supersedes the Smurf SoundFont Editor, and is an entire object-oriented rewrite of it. The supporting libraries are GUI-independant and can be used in your own programs for doing SoundFont manipulation.

SlimServer provides an elegant and easy to use interface for playback of music stored in many audio formats, and supports Internet radio stations, playlist management, Web access, and an infrared remote control. The music remains on the host computer and streams over the network to any streaming audio client.

Nx2 is a somewhat complex Web application that acts as a frontend to music databases. Based on XUL, it runs in Gecko based browsers such as Firefox. Built on this idea is a client/server model where several Nx2 frontends can connect to each other, creating a way to link together databases on different networks.

Python Mesh Viewer is a very basic tool to display
and play with 3D models. You can either construct
them in the code (by defining points, triangles,
and quads) or load them from a file. Currently,
the only file format supported is the ".mesh"
format from the closed source software medit. The
rendering is done with absolutely no hardware
acceleration (no OpenGL).
